A Novel Hollow Fiber Membrane Biofilm Reactor for Esterification Wastewater Treatment

Abstract:

We conducted a series of steady-state experiment on a novel anaerobic-MABR process used for COD removal of esterification wastewater. The results showed that COD removal efficiency remained above 90%, even if the COD loading was up to 3000mg / L, the removal rate still remained above 80%. To ensure the final water quality, biological aerobic segment played a decisive role in anaerobic-MABR process. Hollow fiber membrane is not only a biofilm carrier, but also play the role of non-bubble aeration, oxygen and nutrients, respectively, come into the membrane from both sides of the biofilm.The study suggested that, MABR have a better removal efficiency on COD. The maximum COD removal rate is 85% at hydraulic retention time (HRT) of 24h,oxygen pressure of 0.5atm. The changes of PH, oxygen pressure, and flow rate have little effect on COD removal.
